Delayed response - I only know why I'm upset after a few hours - which makes social interactions hard

Even with my friends, I just can't articulate in the moment why something upset me. I can't even articulate it to myself.

Not just that, I can't explain what I want or why I did something as soon a someone slightly judges me or disagrees. My mind just goes blank.

So I get a lot of misunderstandings, because I only realise what I wanted to say hours or days later (when I'm alone).

If I'm like this with my friends, how will I ever function. I feel extremely isolated and lonely.

Whenever it happens I also go through burnout, I fall into deep depression and it feels like I'm drowning while everybody else is swimming above me.

Do you go through this too? Did it get better? I only recently realised I'm autistic
